Question

what is a homologous series,? with an example.what are its characteristics.​

Answer 1

Explanation:

Characteristics are : The members of the homologous series have same functional group. Members have the same general formula. Members have the almost same chemical properties due to same functional group. Members have common general method of preparation.

Homologous Series

A series of similarly constituted compounds in which the members present have the same functional group and similar chemical properties and any two successive members in a particular series differ in their molecular formula by a -CH2-unit, is called a homologous series.

Characteristics of a Homologous Series:-

• All the members of a homologous series can be represented by the same general formula. Any two adjacent homologues differ by 1 carbon atom and 2 hydrogen atoms in their molecular formula.

• All the compounds of a homologous series show similar chemical properties.

• With increase in the molecular mass, the gradual change in the physical properties occurs, e.g. the melting and boiling points increase with increasing molecular mass.

• The difference in the molecular masses of any two adjacent homologues or members is 14 u.
